The defendant, from Ilford, east London, denied murder, but a jury rejected his explanation and convicted him by a majority of 11 to one after 13 hours and 25 minutes.

He was remanded in custody to be sentenced on Friday.

Mr Khan’s eldest son Khalil Khan said: “My dad was a kind, loving and caring man who would always put others before himself. His death has had a huge impact on our lives, which have now changed forever.

“We had such a happy, caring and joyful family. This has now been destroyed forever by an awful, heartless act that none of us deserved.

“We have been left with a void in our lives that can never be filled. We all miss him so much.”
